PDF signing adds a visual signature element to a PDF document. You create your signature (by drawing, typing, or uploading an image), position it on the appropriate page and location, and the tool embeds it into the document. The output is a PDF that contains your signature as a permanent visual element — identical to what you'd get from printing, signing, and scanning, but without the hardware.
Use cases include:
Signing contracts and agreements received as PDF attachments.
Adding your signature to application forms and official documents.
Signing approval documents and authorization forms.
Adding initials to multi-page documents that require page-by-page acknowledgment.
Signing NDA and confidentiality agreements quickly without printing.
Contracts, forms, agreements — any document that needs your signature can be signed in minutes without printing.
Create your signature, place it, download the signed document.
Upload the PDF you need to sign.
Create your signature: draw it with your mouse or finger, type your name in a signature font, or upload an image of your signature.
Drag your signature to the correct location on the document. Resize if needed. Download the signed PDF.
Upload, sign, download. The signed PDF is ready to send.
Your signature is created using one of three methods: drawing (captured as a canvas image), typing (rendered in a signature font), or uploading (a pre-existing signature image).
The signature is converted to a transparent PNG and embedded in the PDF at the specified location. The embedding uses the PDF's image XObject mechanism.
The output PDF contains the signature as a permanent visual element that appears in all PDF viewers and prints correctly.
Electronic signature addition is an annotation and image embedding operation.
Your signature (whether drawn, typed, or uploaded) is converted to a transparent PNG image.
The signature image is embedded in the PDF as an image XObject and placed as an annotation or directly in the content stream at the specified location.
The output PDF contains the signature as a permanent visual element. The signature is rendered as part of the page content and appears in all PDF viewers.
